DETAILED DESCRIPTION OF THE EMBODIMENTS

The exemplary embodiments will be described in detail here, and examples thereof are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same reference signs in different drawings designate the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

The terms used in the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms “a”, “said” and “the” used in the present disclosure and appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should further be understood that the term “and/or” used herein refers to and includes any or all possible combinations of one or more associated listed items.

It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, first information may be referred as second information; and similarly, second information may also be referred as first information. Depending on the context, the word “if” as used herein can be interpreted as “upon” or “when” or “in response to determination”.

FIG. 1 is a flowchart illustrating a discontinuous reception configuration method according to an example. FIG. 2 is an application scenario illustrating a DRX configuration method according to an example. The DRX configuration method may be applied in a base station. The base station configures at least one band width part (BWP) for a terminal. As shown in FIG. 1 , the DRX configuration method may include the following steps 110-130.

At step 110, a designated DRX parameter is configured for a designated BWP correspondingly.

In the embodiments of the present disclosure, in order to save the power, the base station can dynamically configure the designated DRX parameter used on each designated BWP for the terminal. The designated DRX parameter may include at least one of the following:

- (1-1) a DRX wake-up duration configured for monitoring physical downlink control channel (PDCCH) and/or monitoring physical downlink shared channel (PDSCH);
- (1-2) a DRX inactivity timer configured to delay the DRX wake-up duration;
- (1-3) a short DRX cycle;
- (1-4) a long DRX cycle; and
- (1-5) a DRX short cycle timer configured to enter the long DRX cycle after the DRX short cycle timer expires.

In (1-1), the DRX wake-up duration is used to configure a duration for monitoring the PDCCH and/or monitoring the PDSCH in a DRX cycle. During this duration, the terminal is in a wake-up state.

In (1-2), the DRX inactivity timer is mainly used to delay the DRX wake-up duration. For example, in a later period of the DRX wake-up duration, a network side happens to have a large number of data to be sent to the terminal, and the remaining DRX wake-up duration is not long enough for transmitting this large packet. If the terminal enters a sleep stage at this time, it can only complete the transmission of the packet when the next DRX wake-up duration comes, which increases the processing delay of the entire service. To avoid this situation, a DRX inactivity timer is introduced, which can reduce the data processing delay.

In (1-3), (1-4), and (1-5), the system can configure a short DRX cycle or a long DRX cycle for the terminal according to different service scenarios. If both the short DRX cycle and the long DRX cycle are configured, when the DRX short cycle timer expires, the terminal may enter the long DRX cycle. For example, if a value of the short DRX cycle timer indicates two short DRX cycles, it means that the long DRX cycle is entered without successfully decoding the PDCCH within two short DRX cycles.

In an embodiment, the designated BWP in step 110 may be any BWP configured by the base station for the terminal.

In an embodiment, the designated BWP in step 110 may be a target BWP to which the base station instructs the terminal to switch a BWP.

In an embodiment, the designated BWP in step 110 may be a default BWP and/or an initial BWP for implementing automatic BWP fall back function. The function of BWP to automatically fall back to the default BWP or the initial BWP is: if a currently activated BWP has been inactive for a period of time, the currently activated BWP may automatically fall back to the default BWP, and if the default BWP is not configured, the currently activated BWP may automatically fall back to the initial BWP. The initial BWP is a BWP configured by the base station for the terminal through a system message. The default BWP is a small BWP specifically set by the base station for the terminal so as to save power. In this way, monitoring the PDCCH and/or monitoring the PDSCH on the small BWP can save power.

At step 120, DRX configuration information is generated, and the DRX configuration information is configured to indicate that the designated DRX parameter is to be used on the designated BWP.

At step 130, the DRX configuration information is sent to the terminal for the terminal to use the designated DRX parameter on the designated BWP according to the DRX configuration information.

In an exemplary scenario, as shown in FIG. 2 , a base station and a terminal are included. The base station can configure the corresponding designated DRX parameter for the designated BWP, generate DRX configuration information for indicating that the designated DRX parameter is to be used on the designated BWP, and send the DRX configuration information to the terminal. After the terminal receives the DRX configuration information sent by the base station, the designated DRX parameter can be used on the designated BWP according to the DRX configuration information.

It can be seen from the above embodiment that DRX configuration information is generated by configuring the corresponding designated DRX parameter for the designated BWP, where the DRX configuration information is used to indicate that the designated DRX parameter is to be used on the designated BWP, and the DRX configuration information is sent to the terminal so that the terminal uses the designated DRX parameter on the designated BWP according to the DRX configuration information, thereby realizing the dynamic configuration of the designated DRX parameter used on each designated BWP, improving the flexibility of DRX parameter configuration, and reducing the power consumption for channel monitoring.

FIG. 3 is a flowchart illustrating another discontinuous reception configuration method according to an example. The DRX configuration method may be applied in a base station and is established on the basis of the method in FIG. 1 . The designated BWP is any one of the BWPs configured by the base station for the terminal. As shown in FIG. 3 , when performing step 130, the method may include the following steps 310-330.

At step 310, a binding relationship between BWP and DRX parameter configured by the base station for the terminal is established.

In the embodiments of the present disclosure, when configuring the corresponding DRX parameter for the BWP, the base station can establish a binding relationship between BWP and DRX parameter, and inform the terminal of the binding relationship through the DRX configuration information, so that the terminal can learn the binding relationship between BWP and DRX parameter quickly from the received DRX configuration information.

In an embodiment, the binding relationship in step 310 may comprise a one-to-one correspondence between BWP and DRX parameter, and/or a many-to-one correspondence between BWP and DRX parameter.

For example: BWP 1 is bound to DRX parameter 1, BWP 2 is bound to DRX parameter 2, and BWP 3 is bound to DRX parameter 3.

For another example, BWPs bound to DRX parameter 1 include: BWP 1, BWP 2, and BWP 3.

For another example: BWP 1 bound to DRX parameter 1; BWPs bound to DRX parameter 2 include: BWP 2 and BWP 3.

At step 320, the binding relationship between BWP and DRX parameter is added to the DRX configuration information.

At step 330, the DRX configuration information carrying the binding relationship between BWP and DRX parameter is sent to the terminal.

It can be seen from the above embodiment that the binding relationship between BWP and DRX parameter configured by the base station for the terminal can be established, the binding relationship between BWP and DRX parameter can be added to the DRX configuration information, and the DRX configuration information carrying the binding relationship between BWP and DRX parameter is sent to the terminal, so that when the terminal switches from a currently activated BWP to a target BWP, a target DRX parameter corresponding to the target BWP can be determined according to the binding relationship and the target DRX parameter is used on the target BWP, thereby improving the accuracy of DRX parameter configuration.

FIG. 4 is a flowchart illustrating another discontinuous reception configuration method according to an example. The DRX configuration method may be applied in a base station and is established on the basis of the method in FIG. 3 . As shown in FIG. 4 , when performing step 330, the method may include the following steps 410-420.

At step 410, the DRX configuration information is added to a first system message or first dedicated signaling;

At step 420, the first system message or the first dedicated signaling is sent to the terminal for the terminal to obtain the DRX configuration information from the first system message or the first dedicated signaling.

It can be seen from the foregoing embodiments that the DRX configuration information can be informed to the terminal through the first system message or the first dedicated signaling, thereby improving the reliability of DRX configuration information transmission.

FIG. 5 is a flowchart illustrating another discontinuous reception configuration method according to an example. The DRX configuration method may be applied in a base station and is established on the basis of the method in FIG. 1 . The designated BWP is a target BWP to which the base station instructs the terminal to switch a BWP. As shown in FIG. 5 , when performing step 130, the method may include the following steps 510-520.

At step 510, a BWP switching command for carrying the DRX configuration information is generated. The DRX configuration information includes a target DRX parameter corresponding to the target BWP or indication information for characterizing the target DRX parameter corresponding to the target BWP.

In the embodiment of the present disclosure, the BWP switching command is a command issued when the base station needs to inform the terminal to perform BWP switching. If the BWP switching command includes the target DRX parameter corresponding to the target BWP, when the terminal switches to the target BWP, a DRX parameter used on the target BWP is adjusted to the target DRX parameter included in the BWP switching command.

At step 520, the BWP switching command is sent to the terminal.

It can be seen from the above embodiment that a BWP switching command for carrying DRX configuration information can be generated. The DRX configuration information includes the target DRX parameter corresponding to the target BWP or the indication information for characterizing the target DRX parameter corresponding to the target BWP, and the BWP switching command is sent to the terminal, so that when the terminal switches from the currently activated BWP to the target BWP, the corresponding DRX parameters can be used on the target BWP, thereby realizing the DRX parameter adjustment for BWP switching and improving the practicality DRX parameter configuration.

The DRX configuration method may be applied in a base station and is established on the basis of the method in FIG. 5 . As shown in FIG. 6 , the DRX configuration method may include the following steps 610-630.

In step 610, a DRX candidate parameter set is configured for the terminal.

In the embodiments of the present disclosure, the base station configures the DRX candidate parameter set in advance according to an actual situation and informs the terminal of the DRX candidate parameter set, so that it is convenient for the terminal to obtain the DRX parameter from the DRX candidate parameter set. For example, the DRX configuration information includes indication information for characterizing a target DRX parameter corresponding to a target BWP (for example, the indication information indicates “the second one”), so that the terminal can obtain the corresponding target DRX parameter from the DRX candidate parameter set according to the indication information (for example, obtaining the second DRX candidate parameter in the DRX candidate parameter set as the target DRX parameter).

At step 620, the DRX candidate parameter set is added to a second system message or second dedicated signaling.

At step 630, the second system message or the second dedicated signaling is sent to the terminal for the terminal to obtain the DRX candidate parameter set from the second system message or the second dedicated signaling, and according to the DRX candidate parameter set and the indication information in the DRX configuration information, the target DRX parameter corresponding to the target BWP is determined.

It can be seen from the above embodiment that the DRX candidate parameter set can be configured for the terminal, and the DRX candidate parameter set can be informed to the terminal through the second system message or the second dedicated signaling, which is convenient for the terminal to accurately obtain the DRX parameter from the DRX candidate parameter set when determining the DRX parameter corresponding to the indication information in the DRX configuration information, thereby improving the reliability of determining DRX parameters.

The DRX configuration information includes a first default DRX parameter corresponding to the default BWP and/or a second default DRX parameter corresponding to the initial BWP.

At step 720, the third system message or the third dedicated signaling is sent to the terminal.

The DRX configuration information includes the first default DRX parameter corresponding to the default BWP, and/or the second default DRX parameter corresponding to the initial BWP and the third system message or third dedicated signaling is sent to the terminal, so that when the terminal switches from a currently activated BWP to the default BWP or the initial BWP, the corresponding DRX parameter can be used on the default BWP or the initial BWP, thereby realizing DRX parameter adjustment for realizing the automatic BWP fall back function, also expanding the application range of the DRX parameter configuration, and improving the practicability of DRX parameter configuration.
